What you’ll learn
This short chapter gives you a set of questions to ask data specialists when discussing analytics results. It will help you structure the questions and answers part after a data scientist has presented his or her data to the audience. We will show you three kinds of questions to ask and how to ask them in the most constructive way possible.
Data conversation
Ellen: . . . and this concludes my presentation of our monthly website traffic analysis. I’m now gladly available to answer any questions that you might have.
Harry:Thank you very much Ellen. Um, does anyone have any questions or should we move right on to the marketing plan at this point? We only have about 30 minutes left by the way for that.
Jennifer:Just a quick question Ellen: Will you send us these slides also electronically by e-mail?
Ellen:Sure, I can do that, they are already on our SharePoint server though.
Jennifer:Okay, it would still be nice if you could send them.
Ellen:Okay, I will.
Harry:Excellent. Any other issues? Well then, let’s move on.
William:I’m sorry Harry, I don’t want to slow us down, but I’m a bit confused. Ellen, didn’t you say the data only covers the first half of the month because of server issues? And still, you made recommendations based on those two weeks that affect my department negatively. Plus, you seem to have compared an off-season month with a high-season one in some of your recommendations. This is all a big mess.
Ellen:Um, no we normalised the data for that actually.
William:Whatever. I don’t think we should put your recommendations in the meeting minutes at this point.
Harry:O wow, I think we’ll need a follow-up on this. Let’s do this the three of us, okay? Now on to our marketing plan.
Harry:Thank you Ellen and William for this follow-up opportunity on our website analysis. I guess we should have probed these questions a bit earlier.
Ellen:I must say, with all due respect William, but you really made me look like a fool out there. I hope the marketing council will trust my presentation next month (sighs).
William:I’m sorry but it just didn’t make sense to me to reduce my products’ visibility on your homepage based on just two weeks’ worth of website traffic data. How do we even know we can trust this data?
Ellen:Well, if you had asked me that, then I would have said that we cross-checked our findings with previous months, and they turned out to be consistent.
William:How did you do that?
Ellen:We ran a regression and also compared the results of earlier months with the two weeks’ results from this month and it turned out that ‘new products featured’ was the best predictor for sales. So, we are quite confident that we need to regularly feature new products to engage customers to deep dive into our e-commerce store.
William:Ah okay, I didn’t know that’s what that variable actually meant. I should have asked. I think we could also add a ‘new products featured’ to our subsite actually. Would that be in line with your findings?
Ellen:Very much so but do make sure that they are highlighted as new again in the product listings further on. Our data shows that customers need that extra guidance. Otherwise, many of them give up too soon when scrolling through all the products.
William:Got it!
Ellen:Great question, by the way, I should have perhaps mentioned that in my presentation.
William:It would be great if you could include such pointers in your next presentation.
Ellen:Will do!
Harry:My learning here is that we should definitely spend more time discussing our analytics findings. I’ll allocate fifteen more minutes for Q&A next month. And thank you both for your openness here.
Slowly but surely analytics practices are taking hold in organisations and most professionals are becoming familiar with data-driven decision making. They are using customer data to better target their sales, operational data to streamline processes, HR data to finetune trainings, or sentiment analysis to understand their social media impact, to name but a few examples.
But to make such analytics efforts successful, high-quality dialogues between business professionals and their analytics colleagues are crucial.
In our experience, asking the right questions about the data and its analysis is a key task to get the maximum value out of data and analytics applications (Figure 7.1). To support teams in their collaboration, we have thus compiled particularly useful questions that business people should ask their data scientists whenever they are presented with new data or discuss analysis results together.
The questions that we found particularly helpful can be grouped into three areas.
The first kind of questions are instrumental to better assess the validity and reliability of the data. The second set is helpful to understand what the data scientists have actually done with the data (and why). This prepares the ground for the third type of questions: application-oriented questions are probably the most important ones to turn insights into impact. They enable you to put the analysis results into practice. Still, you can only assess the answers to these questions if you have first asked the other two types of questions.
What are the benefits of asking these three kinds of questions? Let us just mention the main advantages of adding these questions to your analytics meeting repertoire.
So how can you reap these benefits? Let’s examine the repertoire of questions first, and then briefly describe the best way to use them. Read the list below as a menu to choose from. You will never have time to go through all of them in a meeting, nor is that even necessary. But in our experience, picking one to two questions per type makes sense in most data discussion forums.
For every group, we have put the questions in a sequence that makes sense and that allows the analyst to gradually open up (and not shut down or become defensive).
Any analysis can only be as good as the underlying data. You must thus understand where the data came from and if it is fit for use. To assess the data sources and the quality of the data, you can ask your analytics colleagues the following five questions.
Many data analysts love to talk about their techniques, tools and how they generally conduct their work. It is thus important to focus the discussion on the analysis parts that really matter for the subsequent use of the data. The following questions can help you to steer the conversation towards useful data analysis aspects.
Data should be a catalyst for decisions and actions. To help analysts turn data to decisions, ask them the following questions.
A word of caution here: not all analysts see it as their role to make suggestions based on their data. Some see their job as mere data delivery and synthesis. This last set of questions should thus be asked carefully, iteratively and (most importantly) constructively (signalling respect and a willingness to improve together). Try to establish a collegiate atmosphere when talking about the data’s uses. This brings us to the final section on how to ask analytics questions.
Having outlined which questions you should ask in analytics meetings, let’s now turn to how to best ask these questions. You certainly do not want your analytics staff (who may not always enjoy the communication side of their job) to become scared, defensive, or worried every time they meet you to discuss data insights. So, finding the right tone, time, and tenacity for your questions is imperative.
Your tone should be respectful, curious, and non-accusatory. The very advantage of the question format is that you are simply showing interest and want to know more, without casting a judgement or accusing somebody of not doing their job properly. Hence use the power of the (open) question format and avoid leading questions.
The timing of your questions should follow the process outlined above. So, start with simple, fact-based questions and gradually move to more complex and opinion-based ones. Also make sure that you time your questions well in the sense that you do not interrupt your analysts when they are presenting an issue that is clearly very important to them.
Regarding tenacity you should certainly challenge your analysts when they give you an evasive answer. At the same time, you should also show that you trust and respect them, for example when they have repeatedly given you the same kind of answer to a question.
Questions are of course not the only tool to use in such situations. As important as probing for data sources, analysis aspects, and decision consequences is acknowledging the work that has been done. So, don’t forget to give positive feedback to your analytics staff (and listen to their feedback to you) and thank them for their efforts. Frame data discussions as joint learning events and track how you can improve them continuously. In this way you will avoid the most common source of mistakes in management, according to its most revered guru, Peter Drucker, who said:
‘The most common source of mistakes in management decisions is the emphasis on finding the right answer rather than the right question’.
Whenever there is a presentation of analytics or data among a group of people, make sure you reserve time for questions and answers. Pay special attention to these elements:
Possible risks in data Q&A sessions are:
